New congestion charges - inner city road user taxes and regional fuel surcharges - are being proposed as ways of dealing with Auckland's sometimes crippling traffic issues. Can they help mitigate the problem and raise funds to provide for future public transport infrastructure? We hear from: Emeritus Professor of Transport at Imperial College in London, Stephen Glaister, on how it worked for London, and; a partner at Deloittes, Paul Callow, who lead a 2007 NZ Transport Ministry study on whether congestion charges would work for Auckland.
